First of all, this is a project that I'm doing with my partner mleon. He did it with a duinomite, but we've got much more control over system with raspberry.
In this moment, the system is working over a RPi 3b and other over a RPi 1b like a charm.
Basic components:
- 1 Rapsberry Pi
- 2 ADS1115
- 2 Shunts
- 2 Resistors (voltage divider)
- 1 Temperature sensor: DS18B20
- 1 PCF8574P
- 1 Relay module (several channels)
Optional components:
- 1 nodeMCu (Yes, we can control electrical appliances via wifi )
- 1 Relay module (Up to 4/5 channels)
Control:
System is controled by Web and/or Telegram.
In a future:
- Surplus diversion control system.

As you see, we received some information every X minutes. And modify some values, relays status, ....
Well, this system works like a Battery Monitor System too, but cheaper. And a place, where you can get more information. Also, data log for a long time.
This image is from today:
Relays (local or wifi):
We can switch on/off relays manually (Web, Telegram) or automatically (photovoltaic conditions: vbat, ibat, ipanel, temperature, ... and/or by schedule)
More charts:
Historical chart
Batteries, production, ...
Averages
We used Highcharts library.
Stay tuned.
PS. Sorry for my english.
